Mnesia documentation

[Aaron Pankratz]

Hi, in the Mnesia documentation has this code in section 4.3:

          case mnesia:wait_for_tables([a, b], 20000) of
            {timeout,   RemainingTabs} ->
              panic(RemainingTabs);
            ok ->
              synced
          end.

I get and error, "function panic/1 undefined", when I try to use it.
What is that panic function?

Best,
Aaron
